Solr hOCR search

[alxp]

** Update 2024/09/11: The PR has been rebased against 'main' and can now be built with make starter_dev **

What does this pull request do?

Adds configurations to support a search within a paged content object's children for text found in the page object's hOCR.

How should this be tested?

From a clean ISLE-DC instance:

Add this line to build/docker-compose/docker-compose.drupal.yml in the environment: section:

SOLR_HOCR_PLUGIN_PATH: '/opt/solr/server/solr/contrib/ocrhighlighting/lib'

Then from the isle-dc folder, clone this repository with the solr-hocr branch:

git clone git@github.com:Islandora-Devops/islandora-starter-site.git --branch=solr-hocr

Run 'make starter_dev' and wait for it to complete.

Then after logging in as admin:

1. Create a Repository Item node with model 'Paged Content
2. Click on 'Children' and 'Batch Upload Children'.
3. Select Repository Item, Page, File, and Original File on the batch upload page and click Next.
4. Upload one or more TIFF or JP2 files and click Finish.
5. Go back to the Paged Content node, you should see the Mirador viewer and text should be selectable.
6. Click the show sidebar button in Mirador and then click the Search button.
7. In the search box, enter a term you know is in the text of an image you've uploaded.

You should see the search result in the viewer's sidebar, clicking on it should take you to the highlighted result in the viewer.

Not sure what gives with this failing test, it says:

 * Create a sites/default/settings.php file
 * CREATE the 'test_db' database.

 Do you want to continue? (yes/no) [yes]:

In SiteInstallCommands.php line 197:
                                                                               
  Existing configuration directory  does not contain a core.extension.yml fil  
  e.                                                                           
                                                                               

Script drush handling the __exec_command event returned with error code 1

but there's a core.extensions.yml file in the config/sync folder. Running the step locally works as expected.

On today’s call, it was noted that the issue may be related to Drush 13

Not necessarily related to Drush 13, but possibly needing the same fix as is being done in the Drush 13 PR, altering the --db-url: https://github.com/Islandora-Devops/islandora-starter-site/pull/162/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR45
